|The small contact area transfers little heat that is spread by the big
ball (large heat capacity). Moreover heat is lost through big wire section
area (e.g.Ó200Êm). Very low response.
||The small contact area of the thin tip (small heat capacity) absorbs and
transfers the heat quickly. Furthermore, the loss of heat is minimal with
the small wire section area (e.g.Ó25Êm).
||The large and flat contact area absorbs a big quantity of heat.
Therefore, even if there is some loss of heat by the wire section area,
quick and sufficient heat transfer is possible.
